Abstract

PURPOSE:To enable a master station to control a subordinate station whose operation switch is left turned on forgetfully, by resetting the operation switch of the subordinate station by sending a reset signal through the switch operation of the master station. CONSTITUTION:The master station is provided with a transmitter-receiver and connected to the subordinate station by radio. The subordinate station is connected to the line wire via the master station. The master station and subordinate station can make a call freely as interphones. If the subordinate station has the switch left turned on forgetfully and is still in interphone mode, the master station can not send any signal to the line wire, so reset switch 28 of the master station is operated to generate the signal that indicating a busy state by circuit busy signal generating circuit 18 in response to reset signal f3. On receiving the reset signal that the master station generates, the subordinate station resets a flip-flop by a means such as a one- shot multivibrator. In this case, reset signal f3 generated by the master station is favorably used as a circuit busy signal transmitted during service.
